Isolating plastics to analyze pollutants
Professor of marine and environmental sciences Aron Stubbins, working with graduate teaching assistant Erin Tuttle, has published a new paper in Environmental Pollution describing “An acidic/oxidative digestion that quantitatively removes cellulose acetate.” This process “preserve[s] plastics while digesting synthetic cellulose acetate and a range of organics encountered in environmental samples,” thus isolating the plastics for further study. Find “An optimized acidic digestion for the isolation of microplastics from biota-rich samples and cellulose acetate matrices” in Environmental Pollution.

‘Lattice Network for Lightweight Image Restoration’
“Deep learning has made unprecedented progress in image restoration (IR), where residual block (RB) is popularly used and has a significant effect on promising performance. However, the massive stacked RBs bring about burdensome memory and computation cost. To tackle this issue, we aim to design an economical structure for adaptively connecting pair-wise RBs, thereby enhancing the model representation.” Read the paper and see the full list of authors in IEEE Transactions on Pattern Analysis and Machine Intelligence.

‘Going Beyond Binary: Rapid Identification of Protein–Protein Interaction Modulators’
“Kinetic target-guided synthesis (KTGS) is a powerful screening approach that enables identification of small molecule modulators for biomolecules. While many KTGS variants have emerged, a majority of the examples suffer from limited throughput and a poor signal/noise ratio, hampering reliable hit detection. Herein, we present our optimized multifragment KTGS screening strategy that tackles these limitations.” Read “Going Beyond Binary: Rapid Identification of Protein–Protein Interaction Modulators Using a Multifragment Kinetic Target-Guided Synthesis Approach” and see the full list of authors in the Journal of Medicinal Chemistry.

Breakthrough in early osteoarthritis diagnoses, potentially improving patient outcomes
“Early [osteoarthritis] diagnosis is critical. … Computed tomography (CT) has been considered for cartilage imaging … by introducing radio-opaque contrast agents like ioxaglate (IOX) into the joint. IOX, however, is anionic and thus repelled by negatively charged cartilage glycosaminoglycans. … Here we engineer optimally charged cationic contrast agents … such that they can penetrate through the full thickness of cartilage.” Read “Cationic Carrier Mediated Delivery of Anionic Contrast Agents in Low Doses Enable Enhanced Computed Tomography Imaging of Cartilage for Early Osteoarthritis Diagnosis” and see the full list of authors in ACS Publications.

China Insights Series: How Chinese companies are reinventing management control
Professor George Yip gave a presentation in the China Insight Series. “China’s companies have long been acclaimed for their manufacturing prowess and, more recently, for their pragmatic approach to innovation. It’s time to recognize how they are also reinventing management control for the digital era through an approach we call ‘digitally-enhanced directed autonomy,’ which gives employees autonomy while monitoring more precisely how they exercise it.”

‘Highly-Sensitive Label-Free Deep Profiling of N-glycans Released From Biomedically-Relevant Samples’
“Alterations of protein glycosylation can serve as sensitive and specific disease biomarkers. Labeling procedures for improved separation and detectability of oligosaccharides have several drawbacks, including incomplete derivatization, side-products, noticeable desialylation/defucosylation, sample loss, and interference with downstream analyses. Here, we develop a label-free workflow based on high sensitivity capillary zone electrophoresis-mass spectrometry (CZE-MS) for profiling of native underivatized released N-glycans.” Read the paper and see the full list of authors at Nature Communications.

Using deep neural networks to model complex wave patterns
Researchers have “Developed data-driven models to estimate wave parameters and spectra near the” Chesapeake Bay Bridge Tunnel. “To estimate wave parameters and energy spectra near the CBBT, novel composite data-driven models were developed using the wind, water level, and offshore wave data” were used in “deep neural networks” to model a complex wave environment with relatively low computational resources.

‘Mechanical Properties’ paper featured on cover of Advanced Engineering Materials
Associate professor of mechanical and industrial engineering Yaning Li and co-author Siyao Liu have published a new paper titled “Mechanical Properties of Cochiral and Contrachiral Mechanical Metamaterials Under Different Temperatures,” which was featured on the cover of Advanced Engineering Materials, March 2023. From the abstract: “Cochiral and contrachiral mechanical metamaterials are designed by introducing chiral cells with different handedness to the center of the basic chiral cell. Both single-material designs and multimaterial designs are explored. The designs are fabricated via a multimaterial 3D printer, and uniaxial tension experiments are performed in a thermal chamber at two different temperatures.”

‘Erasing Concepts From Diffusion Models’
“Motivated by recent advancements in text-to-image diffusion, we study erasure of specific concepts from the model’s weights. While Stable Diffusion has shown promise in producing explicit or realistic artwork, it has raised concerns regarding its potential for misuse. We propose a fine-tuning method that can erase a visual concept from a pre-trained diffusion model, given only the name of the style and using negative guidance as a teacher.” Read the paper and see the full list of authors in ArXiv.

A bellwether of embeddedness: One professor says that ‘the AI system … keeping me alive is ruining my life’
Professor Laura Forlano writes how an insulin pump AI system, which promised to “dynamically adjust blood sugar when compared to the previous linear system,” has actually required such frequent human-computer interactions as to make it medically detrimental. “Rather than dismiss this particular system as bad engineering,” she argues, “it’s more useful to think of it as a bellwether for a world in which autonomous systems are likely to be increasingly embedded in everyday life.” Read “When Things Go Beep in the Night: The AI system that is keeping me alive is ruining my life” at Data & Society: Points.

‘The Paradox of Adaptive Trait Clines With Nonclinal Patterns in the Underlying Genes’
“Multivariate climate change presents an urgent need to understand how species adapt to complex environments. Population genetic theory predicts that loci under selection will form monotonic allele frequency clines with their selective environment, which has led to the wide use of genotype–environment associations (GEAs). This study used a set of simulations to elucidate the conditions under which allele frequency clines are more or less likely to evolve as multiple quantitative traits adapt to multivariate environments.” Read the paper and see the full list of authors in PNAS.

Disability studies research incorporated into robotic sculpture
Laura Forlano, professor of art and design and communication studies, has had her work featured in a “robotic sculpture” designed by multimedia artist Itziar Barrio. “Some of the sculptures are programmed and inscribed with text that Forlano, a Type 1 diabetic, transcribed from the alert and alarm history from her ‘smart’ insulin pump and then annotated with field notes,” writes Smack Mellon, Barrio’s exhibition space in Brooklyn, New York. The exhibition’s title, “did not feel low, was sleeping,” is sourced from one of the sculptures in Barrio’s collaboration with Forlano. The exhibition ran from March to April, 2023.

‘Automated Grading of Automata With ACL2s’
“Almost all Computer Science programs require students to take a course on the Theory of Computation (ToC) which covers various models of computation. … ToC courses tend to give assignments that require paper-and-pencil solutions. Grading such assignments takes time, so students typically receive feedback for their solutions more than a week after they complete them. We present the Automatic Automata Checker (A2C), an open source library that enables one to construct executable automata using definitions that mimic those found in standard textbooks.” Read the paper and see the full list of authors in ArXiv.
